About Once in a Lifetime

You live in Mistbury, an apparently normal town where you live an apparently normal life with your family. However, you’ll soon discover that this place hides some deep dark secrets and things can heat up very fast…

From infiltrating into a prison, to exploring mysterious mansions and traveling to the other side of the world: embark on an adventure of conspiracies, meeting bizarre characters, living unique experiencies, seducing gorgeous girls and, if there’s time, saving the world.

If Astaroth seizes power, it will be the end for all of us.
Only you can stop him.
Esse est deus.
